together with the standard braking
system.
ESC System Operations
In order to prevent unstable driving
conditions, the ESC system may request
the transmission system to deactivate
gearshifting. The system handles this
request depending on the gear
engaged and on the rpm, and decides
whether to accept it or not.
Driving with Cruise Control
With the Cruise Control function
activated, the transmission system
selects such settings as to provide
enhanced comfort and fuel-economy.
MC Start Strategy (for MC version
only)
With the aim of optimizing standing
starts for performance driving (only
recommended for use in areas closed
to traffic and in accordance with the
Highway Code), the automatic
transmission system is equipped with
quick start strategy.
This strategy is activated when the
following conditions occur
simultaneously:
• AUTO and SPORT modes active;
•
ESC mode off;
• brake pedal depressed. In these conditions, the driver has the
possibility to accelerate and, keeping
the brake pedal depressed, keep the
vehicle standing until reaching an
engine speed between 2300 an 2500
rpm. Then, upon releasing the brake
pedal, have the best standing start
performance.
WARNING!
This strategy must only be used on
vehicles in areas closed to traffic, in
accordance with the Highway Code
and only by skilled drivers.
Transmission Malfunction and
Overheating Conditions Transmission Failure
Transmission function is electronically
monitored to detect abnormal
conditions. If a condition that could
result in transmission damage is
detected, Transmission Limp Home
Mode will be activated. In this
situation, the transmission may
operate only in certain gears, or may
not shift at all.
CAUTION!
In these conditions, we recommended that you stop the vehicle and turn off
the engine for at least one minute.
When restarting the engine, the
self-diagnosis system may cancel the
malfunction, which will in any case be
recorded by the ECU.
A message and the
warning light
in the instrument cluster will inform
the driver about the transmission
failure.
In failure conditions, the transmission
shift lever can however be shifted to R
(Reverse), N (Neutral) and D (Drive)
position.
When shifting to D (Drive) position,
only a few gears will be available,
depending on the malfunction found.
CAUTION!
If a transmission failure is signaled,
take your vehicle to the nearest
Authorized Maserati Dealer as soon as
possible to have the problem
corrected.
If the failure is signaled when the
engine
is started, it means that the
transmission ECU detected a fault
when the vehicle was last used. Also in
this case, take your vehicle to the
nearest Center of the AuthorizedDriving

Drive Mode Controls Preview Drive modes can be set using the
buttons on central console, below the
A/C controls.
Buttons on the central console have
following functions:
• SPORT: to activate/deactivate a
sportier drive mode. In this mode,
the vehicle has a faster throttle
response and suspension/ESC sport
calibration (not recommended on
wet/slippery surfaces).
• ICE (low-grip): to activate/deactivate
the drive mode to ensure increased
control on slippery surfaces as well
as higher energy efficiency.
•
(ESC Off): to exclude/reactivate
the ESC system. • PARK OFF: to deactivate/reactivate
the automatic activation of the
Electric Parking Brake (EPB).
The active mode (in the example:
SPORT) is shown on the instrument
cluster display.
The drive mode can be selected only
with the key in the ignition switch in
MAR (ON) position, even while
driving. For each mode there are
various vehicle settings, that are
automatically set by the system in
relation to the traveling speed, engine
rpm, accelerator position, speed with
which the pedal is depressed as well as
the traveling conditions (uphill,
downhill, curves).
Use the Drive Mode Buttons
Drive modes can be set using the
buttons on central console. Buttons only have two statuses: OFF
and ON. The OFF status (button
released) is the standard function
mode. The ON status is activated by
pressing the button, the dedicated
LED on the button will illuminate.
Unlike the others, the
(ESC Off)
button must be pressed for at least 2
seconds. The SPORT and ICE (low-grip)
modes can be selected both when the
transmission is set to automatic
(AUTO) and to sequential manual
(MANUAL) operation.
NORMAL/SPORT Mode
SPORT mode is activated by pressing
the button "SPORT" on the central
console; the word “SPORT” will
illuminate on the instrument cluster
display.
To return to NORMAL mode from
SPORT mode, press the button again.
Whenever the engine is started, the
system automatically activates
NORMAL mode, even if SPORT mode
was selected before the engine was
last turned off.
NORMAL mode is intended specifically
for comfortable and fuel-economy
driving (low longitudinal and lateral
acceleration); the gears are shifted
with minimum rpm in lowest noise Driving

can be activated at any time and the
system limits the engine speed rate to
3000 rpm in all gears except for the
6th, unrequested gearshifts could take
place.
In any case, it is advisable to
deactivate
SPORT mode before
selecting ICE (low-grip) mode.
When sequential manual gearshifting
is active, regardless of the mode set
(NORMAL / SPORT / ICE), the
transmission will automatically upshift
or downshift when reaching the
minimum and maximum rpm. This is
to prevent engine overrevving or
underrevving.
(ESC Off) Mode
The ESC system is designed to
automatically activate every time the
engine is started and can be
deactivated by pressing
(ESC Off)
button on the central console for
about 2 seconds. The
(ESC Off)
amber warning light illuminates on
the instrument cluster as well as on
the display, where it is accompanied
by a specific message.
The ESC (Electronic Stability Control)
antiyawing system incorporates all of
the vehicle control systems: ABS, EBD,
ASR and MSR (see "Brake and Stability Control System" in this section for
further information).
The system is fitted with a unit that
predicts the vehicle behavior with
extreme accuracy. The system can
detect when the driver is about to lose
control of the vehicle. In this case, it
can activate the brake calipers
individually and engine control, in
order to create a torque sufficient to
resist the vehicle’s yawing moment.
Press
(ESC Off) button again to
reactivate the system.
The
(ESC On) amber warning light
on the instrument cluster flashes
during all the operating phases.
, the system is automatically disabled
and cannot be re-activated. While
driving, this condition is signaled by
the
(ESC On) amber warning light,
that illuminates both on the
instrument cluster as well as on the
multi-function display, where it is
accompanied by the message “ESC
unavailable go to dealer”.
When the engine is started, the system
malfunction is indicated by the
illumination of the
(ESC On) amber
warning light. CAUTION!
• In the event of a fault, and with the
ESC system disabled ( (ESC Off)
button pressed), the vehicle behaves
as if it were not equipped with this
system: however, we recommend
you contact the Authorized Maserati
Dealer as soon as possible to have
the system checked.
• If you have to tow the vehicle with 2
wheels raised, make sure the key in
the ignition switch is in the STOP
(OFF) position. Otherwise, with the
ESC system active (
(ESC Off)
button not pressed), the control unit
will store a malfunction with
consequent illumination of the
(ESC On) amber warning lights on
the instrument cluster and on the
display. Should this occur, contact
the Authorized Maserati Dealer to
have the system repaired.
• In low- and medium-grip conditions
(e.g., rain, snow, ice, sand, etc.) it is
advisable not to activate SPORT
mode, even with the ESC system
active (
(ESC Off) button not
pressed). Driving

(Continued)
• Driving on parabolic curves will
deactivate the system.
PARK OFF Mode
T
o deactivate manual operation of the
parking brake, with the engine on,
press the "PARK OFF" button on the
central console. The words “PARK
OFF” appear on the instrument cluster
display for 5 seconds, after which they
remain displayed but in smaller size.
To reactivate automatic operation,
press the "PARK OFF" button once
again, the words “PARK ON” appear
on the display for 5 seconds.
CAUTION!
• In certain conditions when the
battery voltage is low, the electric
parking brake system may
temporarily be deactivated for safety
reasons. Therefore, typically upon
starting the engine, when the
battery voltage drops, the message
“PARK OFF” may temporarily be
displayed on the instrument cluster,
indicating that automatic operation
is temporarily disabled. • In the case of performance starting,
check that the electric parking brake
is disengaged.
For further information see "Parking
Brake"
in this section.
Sequential Manual Operation
(MANUAL)
In this mode, the transmission interacts
with the driver in order to allow
manual shift and ensure increased
control of the vehicle. The current
mode allows the gear system to
optimize the engine brake action,
remove undesired shifting into higher
and lower gears and improve the
overall performance of the vehicle.
With automatic transmission selected
(D (Drive) position), shift the
transmission shift lever to position “+”
o “–”.
When this mode is selected, the
symbol “+” or “–” illuminates on the
gear display, based on the position of
the transmission shift lever, and the
gear engaged is shown on the
instrument cluster display.
WARNING!
When sequential manual operation is selected, upshifting or downshifting
must be performed manually.
To engage the gears, shift the
transmission
shift lever to one of the
following two positions:
"+" (UP) to engage a higher gear;
"–" (DOWN) to engage a lower gear.
CAUTION!
• However, some conditions will
remain automatically controlled, for
example, when the engine is
overrevving or underrevving, the
system automatically engages a
higher or lower gear.
• If you request a gearshift in
conditions where the engine is
overrevving or underrevving, the
system will not accept the command.
• The ECU is programmed to control
one gearshift at a time, therefore,
fast and repeated actions will not
necessarily result in a gearshift. A
higher or lower gear is engaged only
if the previous procedure requested
has been completed.
When the system refuses to engage a
gear
, an acoustic signal will sound for a
few seconds.Driving

Sequential manual operation can only
be selected from the D (Drive) position
whatever the function (SPORT,
NORMAL) active at the time of the
request. The gear selected by the
automatic transmission will remain
engaged when the transmission shift
lever is moved.
Shifting the lever back to D (Drive),
automatic operation will instantly be
resumed, and a gear will be engaged
based on the driving style and mode
selected.
In the event of a failure of the
sequential manual gearshift system,
the transmission ECU will select
automatic operation.
Gearshift Paddles Operation
In sequential manual operating mode
(MANUAL), upshifting and
downshifting can be controlled not
only with the transmission shift lever
but also with the two paddles
positioned behind the steering wheel.
"+": (UP): upper gearshift paddle.
"–": (DOWN): lower gearshift paddle. Also in automatic transmission mode,
when the transmission lever is in
position D (Drive), you can shift to a
different gear by moving one of the
paddles. This action will temporarily
switch the system to sequential
manual operation.
If you then keep to a constant driving
style (low longitudinal and lateral
acceleration), the gearbox
automatically switches back to
automatic operation.
Gear Shift Indicator Light
In order to improve fuel economy, we
recommend that you shift gears when
the system prompts you to do so. This
will help reduce fuel consumption
without significantly affecting vehicle
performance.
The arrow icon beside the displayed
gear will light up to indicate the
moment the gear change is required. This indicator lights up just before
reaching the required speed for gear
change.
When the new gear is engaged, the
indicator turns off. If the shift runs
late or is not performed at all, the
indicator remains lit for a few seconds
then turns off. As soon as new
conditions requiring further gear
change occur, the indicator light will
illuminate again.
NOTE:
The gearshift indicator will only work
when the transmission is set to manual
sequential operation (see paragraph
"Sequential Manual Operation
(MANUAL)" in this chapter). Driving

Parking Brake” in section “In an
Emergency”).
• “Parking Brake system revision: go to
dealer”
The EPB system requires
maintenance, therefore contact an
Authorized Maserati Dealer to have
the system corrected.
WARNING!
In the event of an EPB failure, take
your vehicle to the nearest Authorized
Maserati Dealer as soon as possible.
Initialize the EPB System after a
Battery
Disconnecting
After the detachment and the
subsequent connection of the battery,
on the instrument cluster display the
warning light will light up.
To initialize the EPB system lift, release
and lift again the lever located next to
the transmission shift lever.
Emergency Disengagement
In case of brake lock with complete
electrical system failure, it is necessary
to act on the electric actuator using
the special tool provided in the tool kit
to release the pressure of the parking
brake shoes (see “Emergency Release of the Parking Brake” chapter in
section “In an Emergency”).
EPB Operation with
Overheated Brakes Driving on mountain roads with steep
slopes or a sports use of the vehicle
could overheat the brake system
components. In these conditions,
parking brake must not be used since
the push of the power actuator might
not be sufficient to ensure vehicle
braking, especially on a slope.
Drive normally without braking to
allow the brakes to cool down a few
minutes before stopping. In this way,
the automatic or manual activation of
the parking brake will ensure vehicle
braking. Parking Straighten the wheels and turn off the
engine.
Before leaving the vehicle, make sure
that the parking brake is fully applied
in automatic or manual mode and
place the transmission lever in the P
(Park) position.
Remove the key from the ignition
switch.
WARNING!
• Always check that the vehicle is
locked before leaving it.
• Never leave children unattended in
the vehicle.
• Do not park the vehicle on paper,
grass, dry leaves or other flammable
materials. They could catch fire if
they come into contact with hot
parts of the exhaust system.
• Do not leave the engine running
while the vehicle is unattended.
CAUTION!
When you need to park the vehicle on
a steep slope, both with the engine on
and off, it is recommended not only toDriving

ESC system brakes the appropriate
wheel to counteract over or under
steering.
• Oversteer - when the vehicle is
turning more than appropriate for
the steering wheel position.
• Understeer - when the vehicle is
turning less than appropriate for the
steering wheel position.
The ESC system has two available
operating modes:
ESC On
This is the normal ESC operating mode.
At each start-up of the vehicle, the ESC
system is set in this mode and should
be used for most driving conditions.
The ESC should only be turned off for
specific reasons as pointed out in the
following paragraphs.
ESC Off
The “ESC Off” mode is aimed for a
more spirited driving experience but
also purposeful for driving in deep
snow, sand, or gravel. The current
mode disables the traction control
portion of the ESC and raises the
threshold for ESC activation, allowing
higher wheel spin than normally
granted by the ESC system. The
(ESC
Off) button is fitted in front of the
transmission shift lever: to deactivate the system see “Drive Mode” in this
section.
WARNING!
In SPORT mode the ESC control
thresholds are higher for maximum
performance on dry road surface. To
ensure maximum security of the ESC is
recommended not to activate SPORT
mode on surfaces with medium- and
low-grip (e.g., wet, snow, dirt, etc..)
with ESC system active (button
(ESC
Off) not pressed).
NOTE:
T o improve the vehicle's traction when
driving with snow chains, or when
starting off in deep snow, sand, or
gravel, it may be desirable to switch to
the “ESC Off” mode by pressing the
(ESC Off) button and remain in this
operational mode no longer than
needed. Once the situation requiring
“ESC Off” mode is overcome, turn the
ESC on again by pressing the
(ESC
Off) button. This may also be
performed while in motion. Anti-Slip Regulation (ASR) The ASR incorporated in the ESC
system avoids skidding of the driving
wheels during acceleration by means
of the engine control unit (spark
advance delay, engine throttle
opening reduction and fuel injection
cut) and the rear brakes.
The ASR system is designed to enhance
vehicle stability and active safety while
driving, especially under the following
conditions:
• internal wheel skidding on curves
due to the load dynamic variations or
excessive acceleration;
• excessive power transmitted to the
wheels, also in relation to the road
surface conditions;
• acceleration on slippery, snowy or icy
road surfaces;Driving

Use of the Engine Breaking-In Today's most modern production
methods are designed to provide
extremely precise construction and
assembly of components. However,
moving parts do undergo a settling
process, basically in the first hours of
vehicle operation.
Do not drive keeping at a constant
high speed rate for a prolonged time.
While cruising, brief full-throttle
acceleration within the limits of local
traffic laws contributes to a good
break-in. Wide-open throttle
acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine
at the factory is a high-quality energy
conserving type lubricant. Oil changes
should be consistent with anticipated
climate conditions under which vehicle
operations will occur. For the
recommended viscosity and quality
grades, see “Refillings” in section
“Features and Specifications”.
A new engine may consume some oil
during its first few thousand
kilometers of operation. This should
be considered as a normal part of the break-in and not interpreted as an
indication of malfunction.
Avoid exceeding 5000 rpm for the first
620 trip mi (1000 km).
After starting the vehicle, do not
exceed 4000 rpm until the engine has
warmed up sufficiently (coolant
temperature: 149-158°F/65-70°C).
While Driving Never travel with the tachometer
indicator approaching the peak rpm,
not even downhill. When the
tachometer indicator is approaching
the peak rpm (red colored zone), take
precautions to avoid exceeding that
limit.
Ensure proper operation of different
devices checking their respective
control telltales. CAUTION!
• Under normal conditions, all red
warning lights on the instrument
cluster display should be off. When
they come on, they indicate a
malfunction. Refer to “Instrument
Cluster” in section “Dashboard
Instruments and Controls”.
• Continuing to drive when a red
warning light is on could cause
serious damage to the vehicle and
affect its performance.
WARNING!
Do not travel downhill with the
engine off, as the servo brake will no
longer function due to the vacuum
decrease and thus after a few braking
attempts, the system becomes totally
inefficient. The power steering will
also lose its efficiency under these
conditions.
